Creamy, comforting Polenta and Mushrooms is one of those simple Italian dishes that feels elegant with very little effort. The earthy mushrooms, buttery onions, and rich Parmigiano create the perfect topping for soft, creamy polenta.
Prepare the polenta according to the recipe directions. Keep warm while you make the mushrooms.
Heat the olive oil in a large skillet over medium heat. Add the onion and cook until soft and lightly golden, about 5 minutes.
Stir in the butter and mushrooms. Cook, stirring occasionally, until the mushrooms release their moisture and become tender and golden brown, about 6-8 minutes.
Add the sage and broth. Season with salt and pepper. Let the mixture simmer gently for 3-5 minutes, allowing the flavors to come together and the broth to reduce slightly.
Spoon the warm polenta into serving bowls. Top generously with the mushroom mixture and finish with freshly grated Parmigiano Reggiano.
Serve immediately while hot and creamy.
Notes
Stir the polenta slowly and consistently to prevent lumps and achieve a smooth texture
Keep the polenta warm after cooking by covering it or stirring in a splash of liquid to maintain its silkiness
Cook mushrooms until deeply golden so they release moisture and develop flavor
Let the sauce reduce slightly so it clings beautifully to the polenta
